Can I symbolize data by the count of attribute matches?

I am trying to symbolize features based on the "Unique values, many fields" Category in the Layer Properties menu. I have a feature layer that is supposed to have 2 fields with unique values to that feature. Can I symbolize features based on whether or not a certain combination of these unique values appear more than once.

For instance, if this was my table

FID Unique value 1 Unique value 2

1 X A

2 X A

3 S B

4 S C

5 M O

6 D O

7 V T

8 G F

Then I would want FID's 1 & 2 to be symbolized in the "both match" symbology class, FID's 3 & 4 to be in the "Unique vale 1 matches" symbology class, FID's 5 & 6 to be in the "Unique vale 2 matches" symbology class, and FID's 7 & 8 in the "Completely unique" symbology class. Is this possible at all?

I'm dealing with 100's of thousands of records, so I will not be able to do this manually via "Unique values, many fields" symbology protocol.
